Description

Linseed Oil, Butyl Ester Epoxidized is a modified vegetable oil derivative where the unsaturated fatty acid chains of linseed oil have been esterified with butanol and subsequently epoxidized. This chemical modification imparts enhanced stability and reactivity, making it a valuable, bio-based intermediate and additive. It is primarily utilized in the formulation of high-performance polymers, coatings, and plasticizers where sustainability and specific functional properties are required.

Application

• As a bio-based plasticizer and stabilizer in flexible PVC and other polymer formulations.
• As a reactive diluent and modifier in epoxy resin systems for coatings and composites.
• As a precursor for polyols in the production of polyurethane foams and elastomers.
• As a lubricant additive to improve film strength and reduce wear.
• In the formulation of environmentally friendly inks and overprint varnishes.
• As a cross-linking agent or co-monomer in specialty polymer synthesis.
• In the production of adhesives and sealants to enhance flexibility and adhesion.
